yellow powder | [Uses]
Dibenzylideneacetone is used as a ligand to prepare palladium catalysts, which are widely used in catalytic hydrogenation, coupling, carbonylation, alkyne ring trimerization, etc. | [Preparation]
Dibenzylideneacetone is obtained by the reaction of benzaldehyde and acetone. The reaction was carried out in aqueous ethanol solution at a reaction temperature of 20-25°C with a yield of 78%. | [Synthesis Reference(s)]

Organic Syntheses, Coll. Vol. 2, p. 167, 1943 | [Biological Activity]
Dibenzylideneacetone (DBA) showed inhibitory activity against Botrytis cinerea Chitinase with an IC50 of 13.10 μg/mL. The MIC of DBA against B. cinerea was 32 μg/mL, and the EC50 values for inhibition of hyphae growth and spore germination were 16.29 and 14.64 μg/mL, respectively. DBA was able to significantly extend the shelf life of cherry tomato shelf life and is a promising antifungal agent for fruit preservation[1]. | [Purification Methods]
Crystallise the ketone from hot ethyl acetate (2.5mL/g) or EtOH. [Beilstein 7 IV 1747.] | [References]
